Hard-won notes on building production Rust — low-latency systems, Solana MEV architecture, fearless concurrency, and moving hot paths to Rust. Written by the engineers doing the work, not a marketing team.
Garbage collectors, jitter, and the tail latency that kills trading systems — and how Rust's no-GC model gives you predictable microseconds.
The real anatomy of a Solana arbitrage engine: event ingestion, parity-tested encoders, transaction-size limits, ALTs, multi-sender routing, and non-bleed safety.
Channels over locks, bounded queues and backpressure, the actor pattern, and how Rust's type system turns concurrency bugs into compile errors.
You don't need a rewrite. How to find the 5% of code burning 80% of your CPU and move just that to Rust — incrementally and safely.
